Thread: Flaw in my code

Main Method:

public class Driver
{
  public static void main(String[] args)
  {
    double distance = 400.48;
    double fuel = 21.4;
    AutoTrip myTrip = new AutoTrip(distance, fuel);
    System.out.print("My car traveled " + myTrip.getDistance() + " miles ");
    System.out.println("on " + myTrip.getFuel() + " gallons of gasoline.");
    double mileage = myTrip.getMPG(); // get miles per gallon
    System.out.println("My mileage was " + mileage + ".");
 }
}

Suppose to Produce:
My car traveled 400.48 miles on 21.4 gallons of gasoline.
My mileage was 18.714018691588787.



What is wrong with my output?

private double miles;
private double gallons;
private double mileage;
 
public AutoTrip(double distance, double fuel, double MPG){
  distance = miles;
  fuel = gallons;
  MPG = mileage;
}
 
public double getDistance()
{return miles;}
 
public double getFuel()
{return gallons;}
 
public double getMPG()
{return mileage;}
